ATTAC Hl NG-SOCKET FOR TUBING.

SPECIFICATION forming part of Letters Patent No. 530,563, dated Decembeififlcl, 1894. Application filed February 18,1894. Serial no. 500.050. (no mode.)

To all whom it may conocrn: v

Be it known that 1, JOHN JAMES YAUTIER, a citizen of the United States, residing at'the city of Brooklyn, Kings county, State of New 5 York, have inventedcertain new and useful Improvements in Attaching-Sockets for Tub ing, of which the following is aspecification.

My invention relates to attaching sockets or end pieces for tubing, such'for'instance as o the fiexibletubing-used for conducting gas from a nipple or burner ona fixture or pipe to an adjacent lamp or heater; or for analogous purposes. 4 The object of the invention is to simplify 5 and improve, the, construction of attaching sockets in such manner as shall promote creased eflicienoy and durability as compared with other devices of this character. q The invention will first be described and then will be defined in claims hereinafter set forth.

Reference is to be had to the accompanying drawings, forming part of this specification,

5 and in which similar numeralsindicate like 'parts in the several views.

Figure l, is a side elevation of my improved attaching socket and a piece of flexible tubing to which it is connected. Fig. 2, is a lono gitudinal central sectionalviewtthereof, with a gas nipple shown in dotted lines within the elastic tip of the socket. Fig. 3, is a sectional side View illustrating the prolonged usefulness of the socket should the outer part of its 5 elastic tip be broken off. Fig. 4, is a perspective view of the elastic tip of the socket, as seen from its inner end, Fig. 5, is apers'pective view of the metallic ferrule of the socket,

, as seen from its outer end; andFigs. 6 and 7,

' c are modifications, hereinafterreferred to. quite necessary that at- It is desirable and jtaching sockets of the class to'which my invention belongs, shouldbe strong and light,

1 f and so formed that they, with the tubing, may 5 be easily'handled and adjusted without injury to furniture or household articles with -;whioh the socket may come in contact.

, .I make my attaching socket or end piece so preferably of rubber, and an inner ferrule with anouter tubular Tlastlc tip portion 1,

ing disconnected? This tubing may belof any. suitable constrnction,-that shown havingthe usual coiled wire foundation incased in or by gelatinous material covered by a braided fabric. a

\ In a' preferred construction, the ferrule 2,

.has an outer'flange portion t, which flares outwardly or tapers-rearwardlyn From the outer end of the flange 4, the sheet metal of the ferrule is pressed or tooled inward to form a shoulder 5, from, the inneredge of which projects outwardly a longitudinal flange or it will be noticed'that the outer part of the flange 4', where the: shoulder 5, joins it, is about flush wither within the outer face or margin of the elastic tip 1, and that this tip .at its intermediate or central portion, is still larger in diameter. Hence the tip forms an .efficient'guard against injurious contact" of themetal ferrule flange .4, with furniture,

glassor other articles. It-willal'sobe seen that the inbending of the sheet'metal of the ferrule to form the shoulder 5, gives chance for ,lodgment of a considerable body or thickness of the elastic ,material of the tip l,,be- Y hind said shoulder, as seen at 1, in Figs. 2, 3, and 7, of the drawings, in order to form by said material, 1,-a secure lock to prevent pulling of the tip 1, from the ferrule 2. I also extend the elastic material of the tip clear back to (or it may be beyond) the inner end of the part 4,;0f the ferrule, as shown at l", in Figs. 2, 3, and 7. of l the drawings, and much farther than would be necessary to alone form the lock above named behind the,

ferrule shoulder 5, andffor the express purpose of giving ample rearward longitudinal prolongation of the elastic material of the tip within the ferrule and behind saidshoulder 5, to make a suflicientlylong bearing surface to receive and securely hold the endof agas' burneror nipple, should'the outer p'art of the tipl, be broken off. The increased tliickness of the elastic material of thetip 1-, bebind the ferrule shoulder 5, at 1, gives corresponding increased lateral expansibilityto assure full entrance of the gas nipple. to position shownjnEig. 3-,

lies about midway ot' the elastic walls in;

3, onto which the i a li ht thin mtal inward on tip and forms a tongueend groove joint therewith.

From the inner end ofjthe flange t, the fer- I rule extends rearwardly to v forrn a hollow stem or shank portion 7, which at its interiot is preferablyprovided withscrew threads 8, which engage the extremity I socketis-screwed. any suitabieg'lue" 'or cement; is-crunay used to make a permanently secure and gas tight connection of the ferrule and tubing. I prefer to produce the screwthreads on or in the ferrulesteruby pressing or tooling the a I lines corresponding with the pitch of the screw threads, as clearly shown in the drawings. By thus form of the tubipg ing the screw threads I am' not only able to use a desirable light metal for the ferrule, but i give increased strength to the ferrule; and the exterior parallel inclined depressions forming the interior threads give a distinctive and pleasing appearance or finish to the socket which is especially effective when applied to the tubing See Fig. l of the drawings.

i prefer to'taper the ferrule stem 7, from its back end to the flange portion t, to cause compression of the extremity of the tubir' 3, as the socket is screwed onto it, andt taper of the stem also provides for reception of tubing of slightlyvarying diameters. lhus,

in every cases secure and tight joint ot the tubing and socket is assured.

I preferte join the tip 1, to the ferrule 2 by vulcanization in ithe mold within which the tip is formed. To do this I place the finished ferrule in the mold and place therein also a mandrel adapted to form the bore or gas-way 9, of the tip. Rubber or its compounds, in plastic condition, is then lowed or forced into the mold, which then is placed into any suitable chamber wherein vulcanization is effected to a sufficient degree to firmly secure the ferrrlle to the tip at all joint surfaces. After removal of the connected parts 1, 2, from the mold, the "surface of the tip is finished in any suitable manner, and the socket is ready for attachment to the tubing.

-It will be noticed that I make the walls of or intermediate portion between its ends. This causes the tip always to bend in. a grad ual curve and to avoid kinking at the central or intermediate part thereby preventing undue contraction or closure of the gas-way 9. The convened contour of the anterior side walls of the tip or its gradual taper toward bothcnds, also imparts a more pleasing appearance than the ordinary cylindrical elastic tips heretofore in use and less rubber or other suitable elastic-material is required to make the tip, which allows a better quality 3 of rubber to be used while producing a lighter,

more elastic and more serviceable tip for the ame first cost than is possible with of this character having ordinary cylindrical or other exterior fornn- When the finished socket is applied to or upon a gas, nipple or burner, 10, the latter will enter about half-way, as indicated by the dotted linesin Fig. 2, of the drawings. Should the outer portion of the elastic tip 1,be accidentally broken or burned off, the socket is "useful or serviceable by reason of the adaptability-of: the inner part of the elastic tip to form a tight joint with the end of the gas nipple and as illustrated in Fig.3, of the drawings. The socket would be useful were its tip broken on close to the flange 6, or to the forward end of the flange 4;, of the ferrule. This is an. important feature, safe and prolonged use of thesocket after its outer part is broken off, and which is not posas it permits sible'vlith other sockets ofthi's class having an interior tubular metal stem entering the bore of the'el'astic tip and the tubing, as this metal stein prevents insertion of the gas nippie, should the tipbe broken off. Further more, it will be seen that I dispense with this last named tubular metal stem used in other sockets, and that I make the socket in or with but two parts, viz: the elastic tip and the ferrule, thereby lessening the expense of manu facture.

in so far as concerns some features of my inventi n it is immaterial whether or no the shoulder and flange portions 5, 6, of the ter- "rule' the used',as shown by Fig'itotthe crawings; ortthe flange portion 6, may alone be dispensed with and the shoulder 5, be retained, as illustrated in Fig. 7, of the drawings. The construction embodying these parts'5, 6, is preferred because it gives larger joint surface for vulcanization of the ferrule to the tip and together with the surface afforded by the outer walls of the inner extremity 1", of the tip, assures a most secure and satisfactory connection of the tip and ferrule.
